Abstract
This study presents a model for evaluating the carbon and energy management performance of suppliers by using multiple-criteria decision-making (MCDM). By conducting a literature review and gathering expert opinions, 10 criteria on carbon and energy performance were identified to evaluate low carbon suppliers using the Fuzzy Delphi Method (FDM). Subsequently, the decision-making trial and evaluation laboratory (DEMATEL) method was used to determine the importance of evaluation criteria in selecting suppliers and the causal relationships between them. The DEMATEL-based analytic network process (DANP) and VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) were adopted to evaluate the weights and performances of suppliers and to obtain a solution under each evaluation criterion. An illustrative example of a hotel company was presented to demonstrate how to select a low carbon supplier according to carbon and energy management. The proposed hybrid model can help firms become effective in facilitating low carbon supply chains in hotels.
Highlights
With the increased consciousness on the issue of climate change, the implementation of energy conservation and carbon reduction in the hotel industry has become significant to address global warming [1,2,3,4,5]
We used a novel combination of decision-making trial and evaluation laboratory (DEMATEL) and analytic network process (ANP) technique called DEMATEL-based analytic network process (DANP) to determine the influential weights of the criteria based on the network relationship map (NRM) of DEMATEL
We present the following results of our proposed multiple-criteria decision-making (MCDM) model that can facilitate low carbon supplier selection in the hotel industry
Summary
Accor Hotels requires their suppliers to evaluate the environmental impact that their sites, products, and services exert on the environment and to set objectives on the quantitative reduction of GHG emissions [18]. Reflecting these trends, companies in the hotel industry must require their suppliers to oversee their GHG emissions and energy management for a long-term collaborative partnership in the low-carbon supply chain. By incorporating the carbon performance into the supplier selection process, Hsu et al [20] proposed a framework that develops a carbon management model with 13 criteria used to manage suppliers in the Taiwanese electronics industry.
